well she was ill a few weeks ago in japan and beijing with a virus so it may be some lingering affects. hope she'll be well enough for fed cup next weekend because she's their best bet on defending their title. you know,for all the disappointments and speculation about her form,petra has been sick and injured quite a lot this season and it may explain why she isn't nearly as confident in herself and why she hasn't been so consistent. i mean relatively speaking she's had a solid season,much better than most following that initial major breakthrough,but it does seem her motivation deep in tournaments has waned this season. i seriously hope petra takes this off-season and works on her belief and focus again.
i agree with you though,even though i was immensely disappointed to see kvitova pull out,the last couple days have really been a great couple days of quality matches. yesterday with vika and kerber and then aga and maria...and today li na and kerber was good. good match between vika and serena today as well. i feel horrible for kerber too because she did so much work in these last two matches only to go out 0-3. it's too bad. even errani managed to scrape through a nice victory today against sam stosur,and she's still in it believe or not,depending on what happens with aga tomorrow.
but it looks like serena is really the one putting it all together this week. she struggled a little today....struggled a bit against kerber in the first match but she is absolutely unwaivered. to be honest,i don't think anybody will be able to take her down. vika tried so hard today and still lost in straight sets. and forget sharapova she's barely won three games in each of their most recent meetings.
